Fieldtrip is a MATLAB toolbox for MEG and EEG analysis. It is developed at the Donders Institute for Brain, Cognition and Behaviour at the Radboud University Nijmegen (the Netherlands).
The toolbox includes algorithms for simple and advanced analysis of MEG, EEG, and invasive electrophysiological data, such as:
- time-frequency analysis
- source reconstruction using dipoles
- distributed sources and beamformers
- non-parametric statistical testing
